CONSIDERATION OF THE PRESENT AND FUTURE MARKET FOR CESIUM-137

摘要

One of the primary problems in the consideration of the present and future market for cesium-137 is the pricing of this radioisotope. Based on present and probable future prices of cesium-137 and cobalt~60 for applications in which either radio¬isotope may be used, it is believed that cobalt-60 will be preferred to cesium-137 if the sources are to be sold and written off in about 5 years or less. On a rental basis (using an AEC write-off in 30 years) cesium-137 will be preferred.
